1. Internet of Things Architecture                         

The Internet of Things is divided into three levels, namely the perception layer, the network layer, and the application layer.

1. The perception layer is composed of various sensors and sensor gateways. Its main function is to identify objects, collect information, and transmit information;

2. The network layer is responsible for transmitting and processing the information obtained by the perception layer;

3. The application layer is the interface between the Internet of Things and users. It combines with industry needs to realize the intelligent application of the Internet of Things.

2. Applicable places

This scheme is applicable to various places inside and outside the smart campus.

3. Introduction to the system scheme

1. Intelligent lighting system

At present, there are many school places and lighting equipment. Most schools are also brightly lit during the day, and there is serious energy waste. The basic IoT intelligent lighting system can effectively control the lighting in the school and realize the intelligent lighting. . The specific implementation principle is: through the switch panel, every lamp in the classroom and on the road can be controlled on the platform or APP side. At the same time, the control center can also obtain the current status of each lamp through the network and system detection.

2. Intelligent air conditioning fan control system

Realize the automation of the air conditioning system adjustment, intelligently adjust the cold and hot temperatures, save energy, and can be matched with other equipment to meet the needs of the scene. The ceiling fan and wall fan in the classroom can be switched intelligently, such as time switch and scene setting switch.

3. Multimedia control system

Through the Techland Internet of Things APP, the LCD touch all-in-one machine, nano blackboard and other teaching equipment are controlled on and off. One-key switch, volume adjustment, HDMI/VGA switch, computer projector on and off, one-key booth and other operations can be performed on the Dineng all-in-one. Different models of the Dineng all-in-one have different operation interfaces on the APP. Scenario requirements can be used for diversified operations.

4. Security monitoring system

How to effectively ensure the personal safety of students and enable them to have a reliable and comfortable learning environment is the top priority of a safe campus. In the current campus environment, the campus network video surveillance system we provide provides advanced security for the school. The technology prevention platform and video surveillance provide an important prevention and control method for a safe campus.

5. Air quality inspection system

With severe air pollution across the country, PM2.5 testing has become particularly important, which is related to the health of teachers and students on campus. Detect whether the indoor air meets the standard through PM2.5, set the standard value, and send an alarm if it exceeds the preset value to monitor the indoor environment in real time.

6. Remote centralized control system

Implement monitoring of the operation of all equipment inside and outside the campus; remotely control the switches of batch or single sensing, perception and infrared equipment, and display the current status in real time; the system automatically diagnoses the equipment status, realizes remote fault alarm and remote diagnosis and maintenance, and effectively reduces the administrator Troubleshoot equipment, greatly improve the efficiency of lighting management; remotely watch the teaching situation of teachers in each classroom.

7. Information operation and maintenance management system

In the case of campus emergencies, managers will send warning messages to classrooms through the platform, and make emergency management well in advance. Administrators at all levels can send and receive station messages and share files. The school uses multiple brands and types of equipment, and the equipment warranty information is difficult to query. The temporary insurance equipment information can be displayed and prompted through the Internet of Things management cloud platform. The temporary insurance time reminder can be set according to the actual situation of the school. For the status of the repaired equipment, you can check the repair status and frequency, so as to determine whether the equipment can be scrapped and avoid potential safety hazards in advance.

8. Intelligent linkage system

Connected to the system equipment, through the system to carry out linkage management of the controllable equipment, configure linkage actions for the equipment, such as: the door is opened with people, the lights are on, the curtains are opened, the air conditioner is on, etc. It can be equipped with multiple different devices, and the corresponding linkage conditions can also be added. At the same time, the equipment can be switched on and off for a fixed time at a fixed time to avoid waste of resources and achieve the effect of energy saving and environmental protection.

9. Authority management system

According to different management levels, set level roles and assign different management permissions to each level role to ensure the normal and orderly use of campus equipment on campus.

10. LoRa management system

Through the system, the campus street lights can be switched on and off regularly, that is, on and off, etc., to achieve real-time control, time-to-time control, and more reasonable red-saving power resources.
